Nature Communications, Published online: 25 May 2026; doi:10.1038/s41467-026-73620-0 Formamidine-based perovskite solar cells promise high efficiency, but additive-induced deprotonation disrupts precursor stability and device performance. Dong et al. use a hydrolyzing ester additive to regulate proton transfer, stabilizing the precursor and achieve efficient, durable devices.

Nature Chemistry, Published online: 25 May 2026; doi:10.1038/s41557-026-02159-w Organic triplet excitons are ‘dark states’, rendering direct photoexcitation from the ground state and efficient phosphorescence difficult. Now it has been shown that attaching chromophores to lanthanide-doped nanocrystals enables spin-exchange-mediated direct triplet excitation and nanosecond-timescale, oxygen-insens…

The electrocatalytic valorization of furfural, a key biomass-derived platform molecule, offers a sustainable pathway for the synthesis of value-added chemicals under mild conditions. In this study, we report the development and application of nanostructured carbon-based electrodes, synthesized via a hard templating approach using SBA-15 silica and carbon precursors (furfuryl alcohol, FA, and glyc…

RDKit has been the dominant cheminformatics library since its open-source release in 2006. It is written in C++, wrapped in Python, and has accumulated nearly two decades of validated chemistry: SMILES and SMARTS parsing, multiple fingerprint types, 2D coordinate generation, 3D conformer generation, MMFF94 and UFF force fields, a PostgreSQL cartridge. Most cheminformatics pipelines assume it is p…

Sulfoxaflor (SXF), a novel sulfoximine insecticide, has been widely used as a substitute for traditional neonicotinoids (NEOs) to control piercing-sucking pests in agriculture. However, its environmental persistence, high mobility in water and soil, and potential toxicity to non-target organisms (e.g., honeybees, aquatic invertebrates) as well as the toxic risks of its long-lasting metabolites (e…

Diclofenac (DCF) is a widely consumed anti-inflammatory drug, frequently detected in aquatic environments worldwide due to the limited removal efficiency of conventional wastewater treatment processes. This work investigates the valorisation of brewery waste into functionalized carbon-based materials to mitigate the entry of DCF into aquatic systems. Biochar (BC) was produced from spent brewery g…

I’m trying to create professional-looking molecular polarity diagrams in LaTeX (using TikZ or chemfig if possible). I need help sketching the partial charges cloud distribution for the following ...

Nature Communications, Published online: 24 May 2026; doi:10.1038/s41467-026-73548-5 A carboxyl-functionalized photocatalyst generates hydroxyl radicals via a catalytic peroxyacid cycle, enabling complete defluorination of industrial-strength perfluorophenol without external oxidants and with >500 h stability under sunlight.

This paper studies the covariance geometry of filter-integrated observables in dynamical-decoupling spectroscopy. We show that the covariance admits a non-commuting additive decomposition,Ctotal=λCflat+CdevC^{\rm total}=\lambda C^{\rm flat}+C^{\rm dev}Ctotal=λCflat+Cdev,where CflatC^{\rm flat}Cflat represents flat filter-overlap geometry and CdevC^{\rm dev}Cdev encodes spectral deformation induce…

We present a geometric restructuring of chemistry within the Koenig framework ofdimensional flow. The period lengths of the periodic table (2, 8, 18, 32) are derived frominvariant combinatorial subspaces of the regular icosahedron under its rotation group A5: the s-period from 2 axial poles, the p-period from faces minus vertices (20−12=8), the d-period from edges minus vertices (30−12=18), and t…

Nature Communications, Published online: 23 May 2026; doi:10.1038/s41467-026-73618-8 Genetic code expansion can be limited by the need to supply non-standard amino acids. The authors design bacteria that perform integrated steps of converting supplemented aldehydes to L-phenylalanine derivatives and incorporating them within proteins.
